what do I do?

All production vehicles today use computerized fuel injection systems to feed fuel and air into the combustion chamber of the engine. ... After that, you have to let the engine warm up. Otherwise, it simply won't run right. Carburetors on cars operated the same way.

Most car manufacturers stopped using carburetors in the late 1980's because newer technology was coming out, such as the fuel injector, that proved to be more efficient. There were only a few cars that continued to have carburetors, such as the Subaru Justy, until about the early 1990's.

A single throttle body EFI conversion kit, by comparison, will set you back $2,000 to $2,500, and a port EFI kit can cost upwards of $3,000 or more depending on the capabilities of the kit and what type of injectors, fuel pump and electronic controls are included.

In carburetor, this is done mechanically and in fuel injection there are electronic sensors to do this. Fuel injection gives better fuel efficiency and throttle response is quicker. Fuel injection engines are trouble free when compare with carburetor engines.
